Linux only detect 4 cores out of 8 when using this patch #2

Closed raspiduino closed 2 years ago

raspiduino commented 2 years ago

Yes, everything still works, but with 4 cores instead of 8.

I have a Samsung Galaxy A6, which has exynos7870 SoC with 8 Cortex-A53 cores. But after applying this patch, Linux only detect 4 cores. The other 4 cores are always set as 0Mhz, or offline (output from CPU Info app, CPU-Z app and SmartPack Kernel Manager). Using htop output 4 cores, lscpu also output 4 cores.

I don't know if Knox (vmm.elf) has the responsibility for starting up these 4 cores?

Any ideas? Thanks!

Also, this log in dmesg repeated many times:

Remove exynos hotplug driver completely. May solve the issue, but not sure.

raspiduino commented 2 years ago

Thanks! I will try it soon!

Thanks! I will try it soon!

I think the issue is with the driver when you are building on ubuntu 20 or later

to disable the driver you can add entry for hotplug driver alone in drivers/soc/samsung/Kconfig and in drivers/soc/samsung/Makefile change obj-$(CONFIG_ARCH_EXYNOS) += exynos-cpu_hotplug.o to obj-$(CONFIG_EXYNOS_CPU_HOTPLUG) += exynos-cpu_hotplug.o

also in drivers/base/core.c find exynos_cpu_hotplug_enabled() and the line before change #ifdef CONFIG_ARCH_EXYNOS to #ifdef CONFIG_EXYNOS_CPU_HOTPLUG

where CONFIG_EXYNOS_CPU_HOTPLUG is the new entry you created.

I build on Debian 11 :)) Thanks for the details

Thanks! All 8 cores worked for now!

NOTE: I have to disable all things releated to CPU hotplug in .config file, including CONFIG_EXYNOS_HOTPLUG_GOVERNOR. How to do this is up to you, you can comment out the code if you like :))
